As the bus crosses the junction, you
will see a set of steel gates, usually locked, behind which lies a sloping
cobbled roadway leading to a tunnel entrance. Last used in 1952, this was part
of an extensive London tram network. The rails are still visible in the roadway
which continued underground all the way to the Embankment near Waterloo Bridge.
A section of the tunnel has been adapted for use today as a car underpass but at
this end it is simply a storage depot for the council road maintenance
department.
